DESCRIPTION:Title: <a href="https://researchseminars.org/talk/VSGS/86/">A 
 unified approach to extremal curves on Stiefel manifolds</a>\nby Irina Mar
 kina (University of Bergen) as part of Virtual seminar on geometry with sy
 mmetries\n\n\nAbstract\nWe present a unified framework for studying extrem
 al curves on real Stiefel manifolds. We start with a smooth one-parameter 
 family of pseudo-Riemannian metrics on a product of orthogonal groups acti
 ng transitively on Stiefel manifolds. We find Euler-Langrange equations fo
 r a class of extremal curves that includes geodesics with respect to diffe
 rent Riemannian metrics and smooth curves of constant geodesic curvature. 
 For some specific values of the parameter in the family of pseudo-Riemanni
 an metrics we recover certain well-known metrics used in the applied mathe
 matics.\n \nThis is a joint work with K. Hueper (University of Wurzburg\, 
 Germany) and F. Silva Leite (University of Coimbra\, Portugal)\n
